Description

Technical Field

[0001] The utility model relates to the field of agricultural irrigation equipment, in particular to a protective shallow buried drip irrigation belt. Background Art

[0002] Shallow drip irrigation is an advanced irrigation technology that delivers water below the surface through pipes to the root zone of crops. This drip irrigation system delivers water directly to the root zone through drip nozzles, achieving precise irrigation of crops. This technology avoids the problems of water loss and evaporation associated with traditional irrigation methods, saving water and reducing water and fertilizer costs.

[0003] Because shallow-buried drip irrigation capillaries and emitters remain in the soil for extended periods, they are subject to compression from roots and soil, leading to a reduction in the water-passing cross-section or blockage. This can prevent irrigation targets from being achieved, causing the irrigation system to fail or even become obsolete. The "protected shallow-buried drip irrigation method" utilizes standard drip tape wrapped in a protective tube, resolving issues such as soil compression, resulting in a reduction in the water-passing cross-section, or even blockage. Because the emitters are also contained within the protective tube, they avoid direct contact with soil and plant roots, reducing the risk of blockage. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a protective shallow buried drip irrigation belt, which quickly soaks the soil at the bottom of the device so that a gap is created between the device and the device, thereby reducing the risk of the soil clogging the water outlet.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a protective shallow buried drip irrigation belt includes a dripper, and a plurality of nozzles are arranged at equal intervals along the length direction of the dripper. A protective tube is sleeved on the dripper, and a water delivery assembly is provided on the end surface of the protective tube facing the soil. A connecting part is detachably connected to the protective tube, and a limiting part is provided at the center position on the inner wall of the connecting part, and the inner wall of the limiting part contacts the outer wall of the dripper.

[0006] As an optimal technical solution for a protective shallow buried drip irrigation belt of the present invention, an internal thread is provided on the inner wall of the connecting portion, and an external thread matching the internal thread is provided on the outer wall of the protective tube, and the connecting portion and the protective tube are connected by threads.

[0007] As an optimal technical solution for protecting shallow buried drip irrigation belt of the utility model, a limiting groove is provided on the outer wall of the protective tube, and a positioning part is provided on the inner wall of the connecting part, and the positioning part is slidably connected in the limiting groove.

[0008] As an optimal technical solution for a protective shallow buried drip irrigation belt of the utility model, the water delivery component is a leakage hole, and a plurality of leakage holes are provided on the protective pipe. The leakage holes are arranged at equal intervals along the length direction of the protective pipe and the leakage holes and the nozzle are in the same direction.

[0009] As an optimal technical solution for a protective shallow buried drip irrigation belt of the utility model, the water delivery component is a gathering platform and a water delivery hole arranged on the gathering platform. The gathering platform is arranged on the inner wall of the protective pipe, and water delivery holes are arranged on the gathering platform at equal intervals along the length direction. The number of water delivery holes is equal to the number of nozzles, and the positions correspond one to one.

[0010] As an optimal technical solution for a protective shallow buried drip irrigation belt of the utility model, the water delivery hole is a cone with different diameters at both ends.

[0011] As an optimal technical solution for protecting the shallow buried drip irrigation belt of the utility model, a threaded guide groove is provided on the inner wall of the water delivery hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By placing the sprinkler head and the drainage hole deep into the soil, the water flow will soak the soil, and the gravity of the soil will increase. This is different from the gravity of the surrounding soil, which will compress the surrounding soil and create a gap between the soil and the bottom of the protective pipe, reducing the risk of the soil blocking the drainage hole.

[0024] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are all conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels. Example 1

[0025] The present application includes a dropper 2 identical to the prior art, such as Figure 2 As shown, a plurality of nozzles 21 are provided at equal intervals along the length direction at one end of the dropper 2 for spraying the water flowing inside the dropper 2. A protective tube 1 is sleeved on the dropper 2 for protection. The diameter of the protective tube 1 is 3 to 5 cm larger than the diameter of the dropper 2. Figure 3 As shown, a plurality of drainage holes 11 are provided at equal intervals on one end of the protective tube 1 near the nozzle 21. Each row of drainage holes 11 is provided with three or more drainage holes to prevent water from accumulating on the inner wall of the protective tube 1. The nozzle 21 sprays water into the protective tube 1 and then flows out through the drainage holes 11. When in use, the protective tube 1 and the drip tube 2 are buried in the soil, and the nozzle 21 and the drainage holes 11 are ensured to face downward. In the process of water flowing into the soil through the drainage holes 11, the drainage holes 11 located below the protective tube 1 can prevent the soil at the top of the protective tube 1 from settling downward and blocking the drainage holes 11. At the same time, because the drainage holes 11 will soak the soil below the protective tube 1, the gravity of the soil in this part is higher than that of other dry soil, so that the soil below the protective tube 1 settles downward, creating a gap between the soil and the bottom of the protective tube 1, thereby preventing the soil below the protective tube 1 from blocking the drainage holes 11 and affecting the drip irrigation efficiency of the device.

[0026] Furthermore, in order to prevent the inner wall of the protective tube 1 from clogging the nozzle 21, the protective tube 1 and the dropper 2 are connected in a sleeve manner as follows: Figure 2 As shown, the inner wall of the end of the protective tube 1 without the water leakage hole 11 is in contact with the outer wall of the end of the drip tube 2 without the nozzle 21, so that a certain gap is generated between the nozzle 21 and the inner wall of the protective tube 1, which facilitates the nozzle 21 to spray water. In order to ensure that it is always buried in the soil and the sleeve is always in this sleeve, the two ends of the protective tube 1 are detachably connected as shown in FIG. Figure 5 The illustrated connection portion 3 has a stopper 31 positioned at the center of its inner wall to support the dropper 2 and maintain it at a specified height. Internal threads are symmetrically positioned at both ends of the connection portion 3, while the end of the protective tube 1 that contacts the connection portion 3 is provided with external threads. The ends of the connection portion 3 are connected to the opposing ends of the two protective tubes 1 via internal and external threads, ensuring a secure connection. Multiple protective tubes are connected by detachable connection portions at both ends, enabling rapid connection and disconnection while ensuring internal sealing. The stopper 31, positioned at the center of the connection portion, secures the dropper 2, preventing water from oscillating during flow.

[0027] When using this device, the dropper 2 is inserted into the protective tube 1. The two protective tubes 1 are connected by the connecting part 3, and the dropper 2 is supported by the limiting part 31 provided in the middle position of the connecting part 3. When the device is used for irrigation, water flows into the dropper 2 and is sprayed out through the nozzle 21 provided at the bottom end of the dropper 2. The water flows through the nozzle 21 and falls into the bottom end of the protective tube 1 and flows out through the leakage hole 11 to drip irrigate the soil at the bottom end of the protective tube 1. Example 2

[0028] On the basis of embodiment 1, the inner wall of the protective tube 1 is provided with the following Figure 6 The gathering platform 13 shown is used to improve the water flow rate. Water holes 14 are arranged on the gathering platform 13 at equal intervals along the length direction. The number of water holes 14 is equal to the number of nozzles 21, and the positions correspond one to one. The gathering platform 13 is an arc-shaped arc concave toward the center and is integrally formed with the inner wall of the protective tube 1. When the nozzle 21 sprays water, the water will accumulate on the end of the gathering platform 13 facing the nozzle 21 and flow through the water hole 14 located in the center. The water hole 14 is a cone with different diameters at both ends. The end with a larger diameter is located on the inner wall of the protective tube 1, and the end with a smaller diameter is located on the outer wall of the protective tube 1. This structure can further gather the water flow while increasing the flow rate of the water flow in the water hole 14, thereby increasing the penetration of the water flow through the water hole 14 into the soil, increasing the speed at which the water flow soaks the surrounding soil, and thereby increasing the speed of the dropper 2 of the device.

[0029] Furthermore, a spiral guide groove may be provided on the inner wall of the water delivery hole 14 so that water flows along the guide groove when passing through the water delivery hole 14 , and the centrifugal force of the spiral is used to increase the flow velocity of the water. Example 3

[0030] On the basis of embodiment 1 or 2, under the premise of ensuring the connection between the connecting portion 3 and the protective tube 1 is firm, the outer wall of the protective tube 1 can be provided with the following Figure 6 The limiting groove 12 shown in the figure is provided with the inner wall of the two ends of the connecting part 3 that contacts the protective tube 1. Figure 7 The positioning portion 32 shown, the process of connecting the protective tube 1 and the connecting portion 3 is changed from the internal and external threaded connection in Example 1 or 2 to the connecting portion 3 being sleeved on one end of the protective tube 1 and rotated, so that the positioning portion 32 slides along the opening of the limiting groove 12 and rotates after contacting one end of the limiting groove 12, thereby ensuring that the connecting portion 3 and the protective tube 1 will not separate during the flow of water.
